To all `whom t may concern;

Be it known that L Gosier E- Tonnen, .e citizen of the United States, Vresidir/1g kat St Paul, in the County 0f Ramsey., end' .State of Minnesota, have invented certain new and useful Improvements yin Film-Clips., of which the folloWiinf.r is a speeeetion- Mr invention relates to a filnn'eliie and the Object iS to Provide e device 'of thlS character byvmeans of which photographic filme may be readily :Suspended for drying purposes after they have been developed, A further object is to provide a devine whioh may be conveniently and readily manufactured and which maybe packed in quantities in a smell space for shipping- Another object is to provide a device which is efficient and reliable when in use so that the films may behandled expeditiously and without damage thereto.

The full objects and advantages .of `my invention will appear in connection with the detailed description thereof, and the novel features embodied in my inventive idea are clearly pointed out in the claims. v

Referring to the accompanying drawings- Figure 1 is a view in longtiudinal section. Fig. 2 is a view in cross-section on the line 2 2 of Fig. 1. Fig. 3 is a side view.

Referring to the particular construction shown in the drawings, a piece of metal is bent intermediate its ends to form two arms 10 and 12, the curved bent portion being preferably reinforced by ribs 14 which are struck up from the material. These ribs increase the resiliency of the spring formed by the bent portion. The end of the arm 10 is provided with a plurality of teeth 16 bent outwardly at a substantially right angle, and adjacent these teeth the material is cut so as to form an integral tongue 18 which is bent inwardly and downwardly for a purpose which will presently appear. The arm 12 is bent upwardly toform a portion 2O extending farther than the teeth on the end of the arm 10 and said member is provided with holes 22 adapted to receive the teeth 16. lThe portion 20 is bent downwardly to form a portion 24 which is rovided with holes 26 registering with the oles 22. The portion 24 is bent upwardly to form amember 28 which serves as a guard for the teeth. The portions 20 and 24 are spaced Vapart the proper distance to form a slot for receiving the edge of a film A -vvhich isp-to `be dried. The curved bent portion connecting the two portions 20 and 24 acts as a stop for the edge of the film when in,- serted after the arm 10 has been depressed as shown in F ig. 1. When the arm 10 is released the teeth 16 come into lengage ment with the film, and in order. to insure that the film shall be firmly held, the toll-tue 18, previously referred to and which passes through a s101330 in the arm 12, isused a finger piece -for pressing the teeth through the film. Since .the teeth pass through both Sets of holes 22 and 26, as yshown in Fig. 2, the film Will be securely held. lVhen the arms 10 is depressed to release the film it is evident that the portion 2,0 will act to a strip the film from the teeth so that the film `is entirely freed from holding engagement.

In order that the clip and the attached film may be readily hung up for drying the film, the arms 10 and 12 adjacent their connecting portion are provided with holes 32 and 34, by means of which the device may read ily be suspended. In order that chemicals and water may readily drain off the curved 1 bend connecting the portion 20 to the arm 12, it is provided with holes 36.

The operation and advantages of my invention will be readily understood from the foregoing description. The entire device is preferably made from a single piece of non-corrosive metal. This metal can be readily cut and stamped into the desired shape. On account of the provision of `a guard for the teeth there is no danger of injury resulting from the sharp points. The finger piece insures that the film shall be firmly held, while the stop for the edge of the film prevents the latter being inserted far enough to be damaged by engagement with the teeth. On account of the fact that the teeth extend into the film through holes in a portion of the device lying adjacent the edge of the film the latter is readily stripped from the teeth. The provision of ribs on the curbed portion connecting the two arms insures a sufficient degree of resiliency, lwhile the holes located adjacent this portion provide for readily suspending the device. The construction is such that chemicals and water will readily drain off' when the device and attached film are in suspended position.

I claim: v

1. A film clip comprising two resilientlyconnected arms, a member at the end of one of said arms forming a slot for receiving the edge of a film, said slot being directed longitudinally outward relatively to said arms, said member being provided with holes, and a plurality of teeth on the end of the other arm adapted to extend through said holes into the edge of the film.

2. A film clip comprising two resilientlyconnected arms, amember at the end of' one of said arms forming a slot for receiving the edge of a film, said slot directed longi tudinally outward relatively to said arms,

i said member being provided with holes, a

plurality of outturned teeth on the end of the other arm adapted to extend through said holes into the edge of the film, and a guard for said teeth.

3. A film clip comprising two resilientlyconnected arms, a member at the end of one of Said arms forming a slot for receiving the edge of a film, said member being provided with holes, a plurality of teeth on the end of the other arm adapted to extend through said holes into the edge of the film, and a finger piece on said lastmentioned arm for pushing said teeth through the film.

4. A film clip comprising two resilientlyconnected arms, one of said arms having its end bent to form outwardly-extending teeth, the other of said arms being bent upwardly past said teeth, then downwardly whereby a slot is formed :for receiving the edge of a film, and finally being bent upwardly to form a guard for said teeth, and a finger piece on said first-mentioned arm extending through a slot in said secondwmentioned arm for pushing said teeth into the film.

5. A film clip comprising a piece of sheet material bent upon itself to form two arms and a resilient connecting member, ribs on said member for reinforcing the same, a member at the outer end of' one of said arms forming a slot for receiving the edge of a film, said slot being directed longitudinally outward relatively to said arms, said last mentioned member bein provided with holes, and a plurality o? outturned teeth on the end of the other arm adapted to extend through said holes into the edge of the film.

In testimony whereof I hereunto affix my signature.
